Additol EHA is an amine coinitiator for radical UV curing. In combination with a hydrogen abstraction photoinitiator such as Additol ITX, it is used in formulations containing unsaturated materials such as acrylates, methacrylates, vinyls and unsaturated polyesters. With exposure to UV light, Additol EHA undergoes a photochemical reaction that generates radicals. These radicals will initiate polymerisation through the unsaturated groups present in the system. The combination of Additol EPH and Additol ITX is especially suited for curing inks and pigmented coatings. PERFORMANCE HIGHLIGHTS Additol CPK is characterised by: Low viscosity Low odor UV curable formulated products containing it are characterised by: Good surface and depth of cure with pigments The final properties of UV cured products also depend on the selection of other components such as oligomers, reactive diluents and additives. SUGGESTED APPLICATIONS: It is typically used at levels of 2-6% by weight in combination with 1-3% Additol ITX, based on the reactive components of the formulation. Applications include: Flexographic inks Offset inks Screen inks Pigmented coatings 2-Ethylhexyl-4-dimethylaminobenzoate. Exhibits low viscosity, low odor good surface and depth of cure. Used in flexographic, offset and screen inks, and pigmented coatings.
